Abstract: The use of genetically modified animals has been studied in scientific research over time as a way to discover new treatments or even a cure for various diseases. Transgenic Adenocarcinoma of the Mouse Prostate (TRAMP) is a model for prostate cancer (PCa) that develops lesions that range from preneoplastic to metastasis. Its similarity to human PCa brings essential knowledge about disease development as well as making possible to investigate different degrees of the tumor profile. We reviewed the literature regarding five important areas relating to PCa progression in the TRAMP model. We also present some useful PCa models comparing them to TRAMP. Furthermore, we investigated the effect of some therapies related to these areas highlighting the best approaches that can delay PCa progression. The revised studies showed that TRAMP cancer stages are well established from 8 to 30 weeks of age, which makes possible to interfere in specific times of PCa development. Moreover, inflammatory and angiogenic blockage before the appearance of malignant lesions retarded PCa progression and showed better results than therapeutical approaches in other phases in TRAMP mice. Reactive stroma is less studied than other areas, although it has been showing a particular relevance in PCa as a milestone in malignant transformation through the modulation of TGF-ß, vimentin, and aSMA. We concluded that even years after its creation, the TRAMP model is still one of the most essential tools for PCa study, as well as for the development of new strategies to prevent the disease
